Contents: Purpose: To compare range of motion (ROM) outcomes of repeated extension versus static stretching of the lumbar spine in healthy adults. Methods: 101 subjects volunteered and were randomly assigned to 1of 3 groups: repeated extension (Group A, n = 33), static stretching (Group B, n = 36), or control (Group C, n = 32). Double inclinometers were used to measure lumbar extension ROM (prone). Measurements were taken at baseline, 4 weeks, and 8 weeks. MANOVA assessed equivalence of the 3 groups for age and initial ROM; chi-square testing assessed gender differences. ROM data were assessed using General Linear Mixed Model Analysis. Alpha was set at 0.05. Results: Both methods of stretching increased lumbar extension ROM at 4 and 8 weeks. The repeated stretching group increased ROM more than the static group. Group A differences were significant comparing 8 to 4 weeks and to baseline. Group B differences were also significant comparing 8 to 4 weeks and to baseline. At 8 weeks, only group A was significantly different than the control group. Conclusion: Repeated and static stretching improved lumbar extension ROM when compared to no stretching. However, repeated extension when compared to static stretching showed greater gains in lumbar extension ROM after 8 weeks of stretching.
